They've already said they are going to implement Android 7 as the OS. All other "apps" are going to be initially built around that. Android 8 just came out so the underlying software is easy to update. Probably minor bug fixes as usual...most problems have been hashed out already especially since it's open source.
My posts are my opinion. I offer no investment advice whatsoever. I have no idea what the OTC is going to do. /rolls dice....
